Is it possible to read info from wideband oxygen sensor (from Honda Civic) with usual voltmeter? Any body did it?

 

Could be.... I think that Idea was presented in other post.....

 

it is easily done, that is how the gage works. It takes the signal from the sensor, how much voltage is in that signal, and triggers the gage to that proper place. All you need to do is figure out what voltage is what.
